I got the OTA and upgraded to GB and now my battery is draining super fast. I've read other threads but not finding anything useful. At night, when I go to bed, I put my phone on sleep mode but in the mornings it's still almost dead. When I go to battery usage to see what's going on, it says Android OS 70 something % or 80 something %. From reading other people's threads, that's A LOT. Why is it using SO much and what do I do? I don't really like GB anyway and prefer Froyo but this is making it worse. If go back to Froyo is it going to keep wanting me to upgrade to GB? I'd appreciate any advice I can get because I don't know what to do!!
